The impact of meteorological conditions on the occurrence of various cardiovascular events has been reported internationally. Data about the Dutch situation are limited.
We sought to find out a correlation between weather conditions and the incidence of major acute cardiovascular events such as type A acute aortic dissection (AAD), acute myocardial infarction (AMI) and acutely presented abdominal aortic aneurysms (AAAA).
Between January 1998 and February 2010, patients who were admitted to our hospital (Catharina Hospital, Eindhoven, the Netherlands) because of AAD (n = 212), AMI (n = 11389) or AAAA (n = 1594) were registered. These data were correlated with the meteorological data provided by the Royal Dutch Meteorological Institute (KNMI) over the same period.
During the study period, a total number of 11,412 patients were admitted with AMI, 212 patients with AAD and 1593 patients with AAAA. A significant correlation was found between the daily temperature and the number of hospital admissions for AAD. The lower the daily temperature, the higher the incidence of AAD (p = 0.002). Lower temperature was also a predictor of a higher incidence of AMI (p = 0.02). No significant correlation was found between daily temperature and onset of AAAA.
Cold weather is correlated with a higher incidence of AAD and AMI.
气象条件对各种心血管事件发生的影响在国际上已有报道。关于荷兰情况的数据有限。
我们试图找出天气条件与主要急性心血管事件（如 A 型急性主动脉夹层（AAD）、急性心肌梗死（AMI）和急性表现的腹主动脉瘤（AAA））的发生率之间的相关性。
在 1998 年 1 月至 2010 年 2 月期间，因 AAD（n=212）、AMI（n=11389）或 AAAA（n=1594）而住进我们医院（荷兰埃因霍温的 Catharina 医院）的患者被登记。这些数据与同期荷兰皇家气象研究所（KNMI）提供的气象数据相关联。
在研究期间，共有 11412 名患者因 AMI 住院，212 名患者因 AAD 住院，1593 名患者因 AAAA 住院。每日温度与 AAD 住院人数之间存在显著相关性。每日温度越低，AAD 的发病率越高（p=0.002）。低温也是 AMI 发病率较高的预测因素（p=0.02）。每日温度与 AAAA 的发病无显著相关性。
寒冷天气与 AAD 和 AMI 的发病率升高有关。
